OIL-BURNER.

Specification of Letters Patent.

Patented Feb. 2, 1915.

Application filed April 8, 1914. Serial No. 830,463.

To all whom it may concern:

Be it known that I, ELKANAH S. (1001:, a citizen of the United States, residing at Dayton, in the county of Columbia and State of \Vashington, have invented certain new and useful Improvements in Oil- Burners, of which the following is a specification, reference being had to the accompanying drawings.

This invention relates generally to oil burners and more particularly to one adapted for use in cooking stoves, ranges and the like.

The object of the invention is to provide an article of this character that shall be exceedingly simple in construction, and easy to install in the ash pit of a stove without requiring any extended change in the structural arrangement of the latter, the burner by reason of its peculiar structure and mode of operation, operating to fur nish the maximum heat units with the minimum consumption of fuel, and in which, further, combustion shall be perfect, so that the deposit of soot upon the burner or any clogging of the gas jets will be prevented.

With the above and other objects in View, as will appear as the nature of the invention is better understood, the same consists, generally stated, in an oil burner comprising a coiled pipe constituting a retort, preferably of truncated cone shape when viewed in elevation, and connecting with which are suit able means of supplying fuel.

Combined with the retort is a novel means for supplying air thereto from above downward, and at the same time from below upward, the result being that by the excess of oxygen supplied and the manner in which it is fed to the burner, perfect combustion is secured.

As a feature of additional novelty, there is combined with the retort a spreader which will operate to deflect the flame from the burner laterally into direct contact with the coils of the retort, whereby vaporization of the oil is eifected and a practically pure or fixed gas is obtained.

Further and more specific details of con struction will be hereinafter more fully described and claimed.

In the accom i anying drawings, forming a part of this specification, and in which like characters of reference designate corresponding parts: Figure 1 is a View in the nature of a diagram exhibiting all parts of The article is shown as consisting of two coiled pipes 1 and 2 forming retorts that are connected and are disposed upon a sheet 3 of asbestos that entirely covers the ash pit a or bottom. Each retort is a counterpart of the other, and may be constructed in any desired number of coils and is of truncated cone shape in general contour when viewed in side elevation. The bottom terminal of each coil is connected by unions 5 and st with fuel supply pipes 6 and '7, and connected with the latter pipes are branches 8 and 9 respectively. These branches are connected by unions with branch pipes 10 and 11 that are disposed parallel with the front of the stove, and with the latter are connected branch pipes 12 and 13 that pro-.

ject through the ash pit door of the stove, and are connected by a pipe 14 disposed parallel with the stove door. The branch pipes 10 and 11 carry two needle valves 15, and connected with the pipe 1% between the valves is a pipe 16 that communicates with an overhead tank 17 to contain the fuel.

The upper coils on each of the retorts are extended downward at opposite angles to each other forming thereby branches l8 and 19, the lower portions of which are bent so as to lie parallel with or upon the asbestos bed 3, and each of these horizontal extensions 20 and 21 carries a burner jet 22, the free terminals of the branches being connected with the unions 4 and 5, and adjacent to each union is a out off or blind coupling 23, the function of which is to prevent passage of oil into the unions l and 5.

One of the essential features lies in the means for supplying atmospheric air to the top of the space inclosed by each retort and to project the same downward therein. This is accomplished by the employment of four approximately hook-shaped pipes 24, two

being associated with each of the retorts, and have their hooks 25 at the upper ends suspended from the top coil of the retort, the lower ends of the pipes being projected through openings formed in the asbestos mat and in the bottom of the ash pit. From this it will be seen that when the burner is in operation, there will be a constant supply of fresh air directed downward within each retort so that perfect combustion will be S6- cured and the deposition of soot be preYent- 7 is employed in conjunction with each burner,

the same being formed of a disk of metal to which is connected the lower end of a rod 28 the upper end of which is formed with a hook 29 to suspend the spreader from the top coil of the retort.

In the operation 01 the burner, the valves 15 are opened to permit the passage of a small quantity of oil into the pipes 6 and 7 and unions 4E and 5, and as far as the blind unions 23. These parts or" the pipes are then heated by any suitable means such as a wood fire to establish vaporization, and as soon as this takes place the burners are ignited, and the heat from the combustion of the gas will continue the vaporization of the oil in the coils. It will be noted that the gas from the ret'ort 1 is fed to the burner of the retort 2, and that the burner of the retort 1 is supplied with ash-om the retort 2' so that the Copies or this patent may be obtained for oil is caused to traverse the longest path pera missible, thus to insure perfect vaporization. In order to permit installing of the burner, the branch I8 is "connected with the horizontal extension 21 by a coupling 30.

. Having thus described my invention, what 1. An oil burner comprising a coiled retort, hool'c- 'shaped' pipes suspended upon the upper coil of the retort for supplying a current of atmospheri eaifr ram-me ns from above downward, and a spreaderdisposed within the coils." v
